Kindly think in the following terms: Currency hedging is a technique used to offset the risks associated with the changing value of currency. The use of currency futures and options transactions to protect the value of investments and cash against fluctuations in exchange rates relative to the currency in which the fund is denominated. A strategy, which aims to reduce an international share or bond portfolio's exposure to exchange rate fluctuation.
Please consider the following In a global financing operations, if a company or a bank is scheduled to receive say 1M Euros after a period of six months and the company does not want to lose money because of foreign exchange fluctuations, the company purchases a put option or a forward contract to purchase 1 M Euros after six months. Now if the value of the Euros increases the company will lose money on the put option and gain money on the actual transaction, thereby protecting itself from unexpected losses. Similarly if the price of the price of the Euros comes down the company will lose on the actual transaction but will gain on the put option and so will not be affected by the price of the Euros.
